azure_cost_estimate

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Estimate' implies a read-only calculation, the description doesn't address important behavioral aspects like whether this requires authentication, what format the estimate returns, whether it's real-time or cached data, rate limits, or error conditions. The description is too minimal for a tool with 7 parameters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise at just 7 words with zero wasted language. It's front-loaded with the core purpose and uses efficient phrasing. Every word earns its place, making it easy to parse while conveying the essential function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 7 parameters, no annotations, and no output schema, the description is insufficiently complete. It doesn't explain what the tool returns (cost breakdown, total amount, comparison data), doesn't address authentication requirements, and provides no context about data sources or calculation methodology. The minimal description leaves too many operational questions unanswered.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description provides no parameter-specific information beyond the generic 'based on usage patterns'. However, with 100% schema description coverage, all 7 parameters are well-documented in the schema itself with clear descriptions and defaults. The description adds no value beyond what's already in the structured schema, meeting the baseline for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose as 'Estimate Azure costs based on usage patterns', which includes a specific verb ('Estimate') and resource ('Azure costs'). However, it doesn't explicitly differentiate this cost estimation tool from sibling tools like azure_price_compare or azure_ri_pricing, which also deal with Azure pricing calculations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. With multiple sibling tools focused on Azure pricing (azure_price_compare, azure_ri_pricing, azure_sku_discovery, etc.), there's no indication of when this specific cost estimation approach is preferred or what distinguishes it from other pricing-related tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
